My interest in Marfan syndrome started many years ago when I was in high school in South Africa. One of my classmates had Marfan. I heard him talk about it, and his words stuck in my mind throughout my medical school and surgical training in the 1970s and 1980s.
Medicine is constantly changing, and often faster than doctors can keep up. Your doctor has to periodically update her knowledge, but she also has to see hundreds of patients a week, which means she could be a little behind the times regarding new advances or the details of all illnesses and syndromes.
